Estado periodontal del segundo molar adyacente al tercer molar mandibular
Contenido principal del artículo
Resumen
Los terceros molares tienen un patrón de erupción inusual. Estudios sugirieron que, debido a la posición y angulación de, se pueden presentar diversas patologías en los molares adyacentes, tales como problemas periodontales y aparición de caries distales. El objetivo de este trabajo es describir el estado periodontal de los segundos molares mandibulares adyacentes a terceros molares mandibulares. Para ello se realizó un estudio descriptivo transversal. Se trabajó con una muestra de 277 pacientes que acudieron a la clínica odontológica de la UCSG para realizar extracciones de terceros molares en el período A-2018. Se realizó un examen clínico intraoral en donde se observaron las siguientes variables: profundidad de sondaje, estado gingival y presencia de caries en segundos molares mandibulares. Además, se revisó las radiografías panorámicas de los pacientes para determinar la posición del tercer molar mandibular y el nivel de la cresta ósea distal de los segundos molares. Los resultados mostraron que la profundidad del sondaje por distal de los segundos molares mandibulares revisados fue normal (de 1 a 3mm) en el 31% de los casos, en tanto que en el 69% se encontraron profundidades mayores a 3mm. Con respecto a la presencia de pérdida ósea en estas piezas, en el 43% de los casos no hubo pérdida, en el 35% de los casos hubo pérdida leve, el 22% presentó pérdida moderada y solo un 1% tuvo pérdida severa. La presencia de terceros molares mandibulares afecta de forma significativa el estado periodontal del segundo molar adyacente, pudiendo generar bolsas periodontales, pérdidas óseas y caries en la zona distal de estos.
